Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for determining a reward object based on a blockchain provided by the present application may be applied to a data sharing system 10 shown in fig. 1A, and referring to fig. 1A, the data sharing system 10 refers to a system for performing data sharing between nodes, the data sharing system may include a plurality of nodes 11, and the plurality of nodes 11 may refer to different users or respective clients of an object in the data sharing system. In the present application, the different users or objects include a rewarder who initiates a current rewarder task, an information source user who uploads or provides asset certification material, and the like, and correspondingly, the node 11 may include a rewarder node and other user nodes except the rewarder node, and the like.
Each node in the data sharing system stores one identical blockchain. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next block. As shown in fig. 1B, the block chain is composed of a plurality of blocks, the starting block includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp, and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.
Each node 11 in the data sharing system 10 may receive input information during normal operation and maintain shared data within the data sharing system based on the received input information, i.e., upload data to the blockchain. In order to ensure information intercommunication in the data sharing system, information connection can exist between each node in the data sharing system, and information transmission can be carried out between the nodes through the information connection. For example, when an arbitrary node in the data sharing system receives input information, other nodes in the data sharing system acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all the nodes in the data sharing system are consistent.
In one embodiment, as shown in fig. 2, a method for determining a bonus object based on a block chain is provided, and this embodiment is mainly illustrated by applying the method to a node 11 in fig. 1A, and may be specifically applied to a bonus party node. Referring to fig. 2, the method for determining a bonus object based on a block chain includes steps S100 to S400:
and S100, acquiring the reported asset certification material of the information source user based on the current reward task initiated by the reward party.
Wherein, the rewarding party can be a judicial institution set in the country such as courtroom (Coirt); the current rewarding tasks, namely, the notification/announcement and the like of a court released to the general public for collecting unpublished and valuable assets owed to debtors; the asset certification material refers to certification material issued by an organization with credit for certifying assets owned by the target object, such as economic certification (house property certificate, vehicle property certificate, etc.), income certification, etc.; the information source user refers to a source user of the asset certification material, and in the application, reporting the asset certification material can be understood as a "reporting clue" provided to the court after the information source user sees the notice/announcement issued by the court. When the court needs to collect asset proof materials owed to debtors, the court first initiates a corresponding current reward task, and specifically, the current reward task can be initiated through a related system (such as a reward evidence management system) or published on a block chain. In a special case, the court may entrust another organization or platform to distribute the current reward task, which is not limited herein.
Optionally, the information source user is a user uploading asset attestation material to the blockchain; or the information source user is a user who provides asset proof material to the rewriter so that the rewriter uploads the asset proof material to the blockchain. Specifically, the information source user may directly upload the asset proof material to the blockchain through other user nodes in the blockchain as the source/source of the asset proof material, or may provide the asset proof material to the court, and then upload the asset proof material to the blockchain through the rewarding side node by the court. The information source user can upload the asset proof material to the block chain in a direct uploading or indirect uploading mode, and the authenticity and the reliability of the asset proof material can be ensured because the data of the block chain cannot be tampered; in addition, when the reward object confirms disputes, the reward object can be judged according to the uplink time of the asset certification material on the block chain, and the fair and fair of the reward are guaranteed.
Step S200, when a reward object corresponding to the current reward task needs to be determined in the information source users, finding asset certification materials matched with the reporting asset certification materials of the information source users on the block chain to obtain uplink asset certification materials corresponding to the information source users.
When the reported asset certification materials of a plurality of information source users correspond to the same asset, determining the reward object corresponding to the current reward task in the plurality of information source users. After the court issues the current reward task, one situation that may occur is that for a certain undisclosed asset owed to the debtor, multiple users find the corresponding asset proof material and save the asset proof material in the blockchain. The multiple information source users claim their asset proof material as the earliest proof material when providing the material to the court for rewarding, however, of the multiple reported asset proof materials corresponding to the same asset, the first uploaded asset proof material is the most authentic, the other materials have upload times all subsequent to the first uploaded asset proof material, the repeated asset proof material is of little significance to the court, and the other materials may be other forms of asset proof material that the user finds after seeing the first uploaded asset proof material. Therefore, it is necessary to screen a plurality of asset identification materials corresponding to the same current asset, that is, to determine one user among the plurality of information source users as a reward object. Specifically, the reward object may be determined from a plurality of information source users by searching for a ul asset identification material on the blockchain that matches each reported asset identification material, and then determining the reward object based on each ul asset identification material. The uplink asset identification material specifically refers to the asset identification material that has been uploaded to the blockchain. The top-up certification material that matches the reporting certification material is, in essence, the reporting certification material itself.
Optionally, after obtaining the reported asset certification material of the information source user, the method further includes: and determining the current asset of the target object corresponding to the reported asset certification material.
Specifically, when the asset certification material is in a text form, the current asset of the target object is determined according to the text content of the asset certification material. The asset certification material can be a material in the form of characters such as a document and a scanned file, and at the moment, the characters can be extracted from the character material, so that the current assets of owed parties can be determined directly through the character contents of the asset certification material, and the determination process is simple and convenient. For example, as shown in fig. 3, the material is a text form of asset certification material, specifically, personal income certification, and text information such as debtor name, identification number, working time, job undertaking, monthly salary, and name of company can be extracted through the text material, so as to help the court to determine the current asset of the debtor according to the text content.
In addition, when the asset certification material is in an image form, image feature extraction is performed on the asset certification material, and the current asset of the target object is determined according to the extracted image features. The asset certification material may be a material in the form of an image such as a photograph, and in this case, the image material may be subjected to feature extraction by a feature extraction algorithm, or may be subjected to feature extraction by a network model or the like, which is not limited herein. After the image characteristics of the image material are obtained, the current assets of owed parties are determined according to the image characteristics, and the accuracy and the processing efficiency of the determination result are high. For example, as shown in fig. 4, the property certification material is a kind of pictorial asset certification material, specifically, a property ticket, and by extracting features of the pictorial asset certification material, information such as a house owner, a sharing situation, a house address, a ranking time, a planning purpose, a floor number, an area, and a distribution unit can be obtained, thereby helping a court to determine the current property of a debt party according to the above-mentioned text.
Further, the current asset of the target object may be determined according to the manual approval result obtained from the asset certification material. After the asset certification material is obtained, the current assets of owed and debt parties can be determined in a manual determination mode through a court or other mechanisms, and the assets certification material in various forms can be flexibly handled.
Step S300, respectively obtaining uplink time of the uplink asset identification material corresponding to each information source user.
Wherein, the uplink time refers to the time when the asset identification material is uploaded to the block chain. In the process of determining the reward object from the plurality of information source users according to the uplink asset identification materials, in order to determine the asset identification material with the earliest uploading time, the uplink time of each uplink asset identification material is firstly acquired, and then the reward object is determined from the plurality of information source users according to the uplink time of each uplink asset identification material.
Step S400, screening the uplink asset certification material with the earliest uplink time, adopting the uplink asset certification material with the earliest uplink time as an effective asset certification material of the current reward task, and determining that a user corresponding to the effective asset certification material is a reward object of the current reward task.
Optionally, after the uplink time of each uplink asset identification material is obtained, the uplink asset identification materials of each uplink asset identification material may be sorted according to the sequence of the uplink time, and then the uplink asset identification material with the earliest uplink time in each uplink asset identification material is determined to be a valid asset identification material according to the sorting result. For example, the uplink times of the i-th, j-th and k-th asset identification materials are 08:50 at 2/9/2019, 13:20 at 1/9/2019, and 07:30 at 07/1/2019/9, and the three asset identification materials are arranged in time order as the k-th, j-th and i-th parts, so that the k-th material can be determined as the asset identification material with the earliest uplink time. It is understood that the upwelled certification material with the earliest upwelling time may be screened in other ways.
And after the earliest uplink asset certification material is obtained according to the uplink time, adopting the uplink asset certification material with the earliest uplink time as the effective asset certification material of the current reward task, and determining the information source user of the effective asset certification material as a reward object so as to provide the reward for the reward object. For example, for the ith, jth, and kth asset identification materials, after the kth asset identification material is determined to be the asset identification material with the earliest uplink time, the kth asset identification material may be adopted as the valid asset identification material, and the ith and jth asset identification materials may be invalid asset identification materials, and reward prizes may be awarded to the information source users of the kth asset identification material.
It should be noted that the words "valid" and "invalid" used in the present embodiment do not refer to the fact that the asset proves that the authenticity of the material is valid or invalid, but refer to the fact that the material acts as valid and invalid during the rewarding process, wherein the material acts as the effect of the current asset for the first determination of owed parties. For a certain current asset of a debtor, such as a house, if the asset certification material with the earliest uploading time can determine that the debtor currently owns the house for the first time, the asset certification material with the earliest uploading time can be regarded as the 'effective' asset certification material; while other proof of asset materials may also determine that the owed party currently owns the house, but not the first confirmation that the house has been previously confirmed, so that the subsequent confirmation is an "invalid" confirmation. The "valid" and "invalid" used in the description of the asset identification material in the other embodiments have the same meaning as in the present embodiment.
In the embodiment, the asset certification material provided by the user is stored in the blockchain, the blockchain can provide the uplink time of the material, and the data of the blockchain cannot be tampered, so that when the reward object needs to be determined from the information source user, the user providing the asset certification material at first can be determined as the reward object according to the uplink time provided by the blockchain, and the uplink time cannot be changed, so that the accuracy and the reliability of the certification time are improved, in the process of determining the reward object, disputes in the processing result of determining the reward object can be avoided, and the fairness and the justness of the reward are ensured.
In one embodiment, as shown in fig. 5, finding asset identification materials matching the reported asset identification materials of each information source user on the blockchain to obtain the uplink asset identification materials corresponding to each information source user includes steps S210 to S220.
Step S210, performing hash operation on each reported asset certification material to obtain a hash value corresponding to each reported asset certification material;
step S220, finding asset certification materials with the same hash value as the reported asset certification materials on the block chain, and obtaining the uplink asset certification materials corresponding to the information source users.
The blockchain is a decentralized database, that is, any user having a node in the blockchain can upload data on the blockchain through the corresponding node for storage. In the process of uploading data, a user needs to perform hash operation processing on the data to obtain a hash value corresponding to the data. The Hash operation refers to a calculation method for converting an input with any length into an output with a certain length through a Hash algorithm, and the Hash algorithm may be an MD5(Message-digest algorithm5, information digest algorithm 5) algorithm, an SHA (Secure Hash Standard ) algorithm, and the like, and is not particularly limited. For a certain asset proof material, the hash value stored on the blockchain is fixed, so that the uplink asset proof material identical to the hash value can be searched on the blockchain according to the hash value of the reported asset proof material, and the historical uploading record of the reported asset proof material on the blockchain is obtained, so that the corresponding uplink time can be conveniently obtained.
In one embodiment, the method for determining a bonus object based on a blockchain further comprises: and when one current asset only corresponds to a single reported asset certification material, determining the single reported asset certification material as a valid asset certification material. For a certain unpublished asset owed to a debtor, such as a vehicle, in the reported asset certification material provided by an information source user, if only a single reported asset certification material corresponds to the vehicle, because the awarded target determination dispute does not exist, the reported asset certification material can be directly adopted as an effective asset certification material, so that the processing flow is simplified, and the rewarding task processing efficiency is improved.
In one embodiment, as shown in fig. 6, the step S300 of respectively obtaining uplink time of uplink attested materials corresponding to each information source user includes steps S312 to S314.
Step S312, respectively obtaining a first type of time stamp corresponding to each uplink asset certification material;
step S314, the uplink time corresponding to each uplink asset identification material is extracted according to the first type of time stamp.
Wherein, the first type of time stamp is the time stamp written into the block chain under the condition of not changing the structure of the block chain. Referring to fig. 1B, the first type of time stamp may be written into the block body, i.e., stored together with the asset identification material in the block body. In addition, the first type of timestamp written into the block chain is a trusted timestamp, so that the absolute accuracy and the reliability of the timestamp are guaranteed, and the absolute accuracy and the reliability of the uplink time are further guaranteed.
In one embodiment, as shown in fig. 7, the step S300 of respectively obtaining uplink time of uplink attestation materials corresponding to each information source user includes steps S322 to S324.
Step S322, respectively determining the block head of the block where each uplink asset identification material is located, and acquiring a second type timestamp corresponding to each uplink asset identification material from the block head;
in step S324, the uplink time corresponding to each uplink asset identification material is extracted according to the second type of timestamp.
The second type of time stamp is a time stamp written in a block header structure of the block chain. Referring to fig. 1B, the second timestamp may specifically be a timestamp in a block header of the block chain. The second type of timestamp in the block header is a trusted timestamp, so that the absolute accuracy and the reliability of the timestamp are guaranteed, and the absolute accuracy and the reliability of the uplink time are further guaranteed.
It should be understood that, under reasonable circumstances, although the steps in the flowcharts referred to in the foregoing embodiments are shown in sequence as indicated by the arrows, the steps are not necessarily executed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
